Citroen C5 Mk1 2.2 Hdi Cat temperature sensor connection

[yoseff]

Before i disassemble a lot of stuff to find where is the connector for the Catalytic Converter Temp Sensor (2) connection , could someone who knows its location enlighten me?
I know where is the sensor , but then the wire goes up, and i'm not sure what i should disassemble to reach its connection. I wanna test it as it seems to have wrong readings.
Have car on ramps, but wanted to avoid disassemble more than needed to reach the connector.

In this , it seems that it goes up? Is it in engine compartment?

If this is for your 2.2 then it's not the correct diagram, just so you're aware.

The gas temperature sensor (upstream of the catalytic converter) goes directly to the engine ECU.

Hum... But it seems pretty similar to what i have there. So it means that that 2 will connect to the ECU? Because i have something like that there...

Sorry, something happened after posting - had a few issues to deal with elsewhere and my post got a bit garbled. I've corrected the gibberish now.

Yes, the other end of the sensor goes to the engine ECU.

Great. Now i just need to find where is the engine ECU
I knew that in the Activa (Both Suspension and Engine) , but must look for it in the C5.
Any clues on the color of the connector there? Or that will be obvious once i find the ECU?

Here's the engine ECU for your specific C5.

1344 is the Upstream Exhaust Gas High Temperature Sensor. You can see that the 2 wires of the sensor (1389) on pin 1 & (ME480) on pin 2 go to the 48 pin Brown connector on the engine ECU on pins F3 and E3
